Cooling water tower

Abstract

A cooling water tower has a water container, a fan motor, a controller, an air outlet, a first sensor, a second sensor, a pump, and an air conditioning device. The air conditioning device has an air cooling condenser, a freezing agent control device, a compressor, and an evaporator. The air outlet is disposed on a top portion of the water container. The first sensor is disposed on the air outlet. The second sensor is disposed on the bottom of the water container. The fan motor is disposed on the top portion of the water container. The controller is disposed on the fan motor.

I claim: 
     
       1. A cooling water tower comprises: a water container, a fan motor, a controller, an air outlet, a first sensor, a second sensor, a pump, and an air conditioning device,   the pump pumps water from the water container to the air conditioning device,   the air outlet disposed on a top portion of the water container,   the first sensor disposed on the air outlet,   the second sensor disposed on the bottom of the water container,   the fan motor disposed on the top portion of the water container, and   the controller disposed on the fan motor.   
     
     
       2. A control system of a cooling water tower comprises the steps of: starting a rotation of a fan motor and an operation of a controller,   setting a predetermined temperature value Ts, and detecting a temperature value Ta of a water container,   determining whether Ta is larger than Ts,   determining whether Ta is larger than Ts plus a predetermined difference value X,   if Ta is larger than Ts plus X, the fan motor rotates in a full speed,   if Ta is less than or equal to Ts plus X, the fan motor rotates in proportion to Ta,   determining whether Ta is less than or equal to Ts, if Ta is less than or equal to Ts, the fan motor rotates in a lowest speed.   
     
     
       3. The cooling water tower of claim 2 wherein the air conditioning device comprises an air cooling condenser, a freezing agent control device, a compressor, and an evaporator, with the pump pumping water from the water container to the air cooling condenser.
